Specification of Letters Patent.

Patented Apr. 6, 1915.

Application filed December 30, 1914. S rial No. 879,64;

Ta all whom it may concern: I

Be it known that I ALBERT JOHNSON, a citizen of the United States, and a resident of the city of New. York, borough of Manhattan, in the county and State of New York, have invented a new and Improved Car-Window Cleaner, of which the following is a full, clear, and exact description.

The invention relates to a window cleaner particularly intended for removing frost, rain and the like from the transparent member positioned in front of a motorman.

The object of the invention is to provide a simple, strong and eflicient window cleaner which can be easily and quickly attached to or removed from a window frame and whereby the outer surface of the window can be wiped from within without disturbing the window frame.

With the above and other objects in view, the nature of which-will more fully appear as the description proceeds, the invention consists in the novel construction, combination and arrangement of parts as herein fully described, illustrated and claimed.

In the accompanying drawings, forming part of the application, similar characters of reference indicate corresponding parts in all the views, and Figure 1 is an elevation of a car window provided with an embodiment of my invention; Fig. 2 is a vertical section through the cleaner on line 22, Fig. 3; and Fig. 3 is an elevation of the cleaner from the inner side of the car with the operating handle broken off.

Referring to the drawings, 4 represents a transparent member mounted in a suitable window frame 5. Secured to the central part of the lower brace of the window frame is a socket 6 provided with an elliptic flange 7. The socket proper projects through the brace with the flange resting against the outer surface of the brace, to which the flange may be attached by any suitable means. Mounted to rotate in the socket is a crank or handle 8. The ]0l1I- naling portion of the handle 8 has 1ts end projecting through the socket at the flange 7. Mounted to turn on its pro ecting end is a link 9, to Which link a squeegee 10 is pivotally attached. Connected to the journaling end of the crank 8 adjacent the link 9 is an arm 11 which is constrained toturn with the handle 8. The arm 11 engages the squeegee 10, the engaging end of the arm being bifurcated to straddle the frame of the squeegee which carries forming the wiper.

In the normal position of the device, a pin 12 which connects the squeegee 10 to the link 9 is to one side of the arm 11, that is, off center. As the arm 11 is rotated by means of the handle 8 from the left-hand position in Fig. 1 toward the right, the pin 12 will remain eccentric until the same comes in engagement with the elliptic flange 7, where further movement of the link 9 is arrested and the squeegee 10 continues to turn by the arm 11 alone, whereby the said pin 12 is brought to the" other side of the arm 11 (see the right-hand dotted position in Fig. 3). In the returning movement of the squeegee the reverse will take place, that is, the pin 12 will remain to one side of the arm 11 until the said pin 12 comes in contact with the left-hand portion of the flange 7 and again the pin is centered with reference to the arm 11 by pushing the pivot across the arm. It may be remarked that the link 9 forms an articulated portion of the squeegee whereby the turning point of the squeegee is normally maintained to one side of the'arm, and always it lies to that side of the arm toward which the squeegee is to be rotated to clean the window.

From the foregoing description, taken in connection with the accompanying drawings, the advantage of the construction and operation of the device shown will be readily understood by those skilled in the art to which the invention pertains; and while I have described the principle of operation, together with the device which I now consider to be the best embodiment thereof, I desire to have it understood that the device shown is merely illustrative and that such changes may be made as are within the scope of the appended claims.

Having thus described my invention, I claim as new and desire to secure by Letters Patent: v

1. In combination with a window, a socket made to project through the brace of the window-frame, said socket having an elliptic flange whereby the same can besecured to the brace, a handle mounted to turn in said socket, a link mounted to turn on the portion of the handle engaged in the socket and positioned adjacent said flange,

the flexible part a squeegee, a pin connecting the squeegee to the link, and an arm attached to the. handle adjacent the link and constrained to rotate with the handle, said arm engaging the squeegee, said pin adapted to engage the flange and form a stop for the movement of the link when the handle is rotated.

2. In combination with a window, a device of the class described comprising a socket made to project through a brace of the window frame, a handle mounted to ro- V tate in said frame, a squeegee having an articulated end formed to turn on the end i of the handle mounted to turn in the socket,

elliptic flange whereby the flange may besecured'to the outer face of the brace, a handle located on the inner side of the window and having a portion thereof mounted to rotate in said socket, a squeegee having an articulated portion engaging the end portioni'lmounted to turn in the socket at the flange, an arm connected to the handle .at the articulated portion so that the same is constrained to rotate with the handle, vsaid arm straddling the squeegee so that the same is free to move longitudinally ofgsaid arm but is constrained to move laterally with said arm, said flange forming a stop for said articulated portion of the squeegee at predetermined points.

4- In combination with a window, a device of the class described comprising a handle mounted to turn in the brace of the window frame, a squeegee having an articulated portion mounted to turn on said handle, an arm constrained to rotate with the handle and engaging the squeegee above the articulated portion, said articulated point of said squeegee lying normally to one side of said arm and always on the side toward which the squeegee is to be rotated.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

ALBERT JOHNSUN.
